1H-NMR as a tool for determination of mixtures of virgin olive oil with oils of different botanical origin.

Funded under: FP5

Abstract

1H-NMR spectroscopy provides a possible alternative to conventional chromatographic methods for determining the composition of oils. In this study, various oils from olive, hazelnut and sunflower were analyzed by 1H-NMR spectroscopy. Experimental conditions were chosen in order to have a short experimental time. It was demonstrated that multivariate statistical methods, in particular discriminant analysis, applied to selected predominant peaks in the 1H-NMR spectra of oils resulted in a good separation between these oils of different botanical origin and permitted the detection of their mixtures.
